I am looking to purchase my first Japanese sword and I'm looking for help in choosing between two WW2 Naval Kai Gunto swords which are both listed by online dealers. To my novice eye they both appear to be similar and are both about $1600 USD. They both have a naval anchor stamp and appear to be stainless. My main questions are do they both appear to be genuine, are they worth the price asked and if so which appears to be the better sword? I am concerned that both scabbards only have single hangers, as all other Kai Gunto that I've seen have two hangers. Thanks for taking the time to read this. This is my first post so I appologise if I have posted this in the wrong place or the pics dont come out.
